Keyless Repeater: Complete Guide

What is a Key Repeater Device?

A keyless repeater is a equipment that boosts the transmission from your car key fob. This technology allows wireless entry to automobiles equipped with keyless entry systems.

Repeater systems are commonly used for legal applications such as vehicle testing and penetration testing.

How Does a Keyless Repeater Work?

The signal amplifier works by detecting the LF signal from your remote key and sending it to your car. Here’s the process:

1. The signal repeater picks up the signal from the key fob
2. It strengthens the radio frequency
3. The enhanced frequency is relayed to the vehicle
4. The automobile authenticates the key signature
5. Access is granted as if the key fob were close
